Minecraft hangs on the initial loading screen whenever it exits forcibly, ie. because of a FamilyLink limit, or if Android stops it when it runs in the background. 

The only cure I found so far is to deinstall and install it again. Clearing data, and cache has no effect. 

This issue is reproducible 100% of the time on a Huawei MediaPad T5, and on a Huawei Mate 20. One has data set to extern, but not the other. 

This bug might be related to MCPE-31185, but its description was different enough so that it might be a different problem.

If you need anything else, please tell!
